The technician installed a new AC split without a vacuum pump. (Gree 24000 BTU Inverter)

Should we drain the refrigerant, do vacuum, and refill the refrigerant?

It is written in the AC manual that we should vacuum during installation.

I read that air and humidity are harmful for the system and the compressor.
